"The `topsfnernb'e'r lill carries fthe extended threaded'frmember:v 36 :and 'has `an annular .opening 40 into the air chamber I9.

The operation of the device is as follows:

The member I6 isplaced between the flange 50 of the carburetor manifold r5I and the flange 52 of the air intake manifold 53 and attached thereto by means of bolts passing through the openings I8, I8 of the member I6 and corresponding openings through the flanges 50 and 52.

The engine is allowed to run at idling speed and the position of the piston 22 is adjusted by means of the threaded bolt 2I lso that the opening 39 of the valve 31 is close to the edge of the opening di) of the top I0, retaining, however, the opening it in closed condition. v

In this position, the engine is at its greatest vacuum, except when the vehicle is decelerating,

l and vacuum in the intake manifold 53 is transmitted to piston 22 through air passage I9 and passage 2I tothe vacuum chamber 20.

When the speed is decelerated, the vacuum in-V creases, the piston 22 is drawn inwardly toward vthe spring 25, causing the pin V34 to move inwardly resulting ina revolution of the valve 31 and a gradual opening of the opening 40 and allowing air tobe drawn through the openings,V

42, 42, the openings '39 and 40 into the air-chamber I9, which being' connected withv the intake manifold 53 reduces the vacuum-and tends to maintain it at the idling speed vacuum.

- Inother devices designed for the purpose of eliminating fumes, the employed valve is held on its seat by the usually employed spring valve, that is, by means of a spring fixedly attached to the valve stem. It is obvious that in spring load- `ed valvesof this construction the spring tension [on the valve must approximately equal the vacuurn pull on the valve head, and hence the valve is held very lightly upon the seat, permitting air to leak into the intake manifoldtending toward irregular running ofV the engine at idling speed.

This defect is overcome in my device in which the vacuum tends to hold the rotating valve 31 against the casing at all speeds except when the two openings 39r and 40 are in complete alignment and the opening 40 entirely open, in which position the vacuum is materially reduced and the valve 3l is free to return to its normal position.

It will thus be seen that my device is adapted to maintain a practically uniform vacuum in an internal engine during deceleration irrespective of its speed and to thus maintain a combustion, or explosive, mixture commensurate withv the ability of theI engine to consume, or ignite, it, thus preventing the exhaust discharge of objectionable and `irritating gas mixtures of unconsumed or partially consumed gases.
